Abstract (en)
[origin: WO2021090068A2] The present invention provides a modified diene copolymer composition having a modified A-B-C or C-B-A copolymer comprising at least one conjugated diene monomer and at least one unsubstituted vinyl aromatic monomer and at least one substituted vinyl aromatic monomer, wherein each block or segment in the modified A-B-C or C-B-A copolymer is either a homopolymer or a copolymer comprising at least one conjugated diene monomer and/or at least one unsubstituted vinyl aromatic monomer and/or at least one substituted vinyl aromatic monomer, wherein any of the copolymers have a distribution configuration that is tapered, counter tapered, random or controlled, and wherein any of the homopolymers or the copolymers comprising at least one conjugated diene monomer and/or at least one unsubstituted vinyl aromatic monomer may be in-chain and/or chain-end modified with at least one unit of at least one substituted vinyl aromatic monomer; optionally having a block copolymer made from the modified A-B-C or C-B-A copolymer, wherein the block copolymer comprises at least two of the modified A-B-C or C-B-A copolymers. The invention also provides a process for making the modified diene copolymer composition.
